Forge crash on startup

[Tune]

I am using the 1.7.10 version of forge, and when I run it without mods in the mod folder, the game opens fine, but whenever I put any mods in the folder, it crashes before even opening the game. I have no idea what I'm doing, as I'm new to modding in general.

You need to update, 1.7.10 is no longer supported on these forums.

 

It is stated in the EAQ that old versions are not supported here: http://www.minecraftforge.net/forum/topic/20-rules-and-eaq-read-first-or-you-will-get-banned/

That's kind of... obscene, but w/e. Thanks for letting me know.
